The object of this invention istoprovide,v a" gate mounted to move with reference toa lowei` horizontal axis,'fio'm vertical position to a horizontalv and openyposition, thev return movement under the action of a counter'- balance, being checked bythe'operation of a governor. Y y

A further. object is toV provide, lin connection with a gate Inou'nted'as specified, a

lo cable connected with the gate, adrum for the cable, and means controlling the speed of rotation of the drum in one direction, vsaid dru'in'being' freely rotated during the opening movement of the gate, and speed being checked, during the closing movement, by the special means hereinafter disclosed.

view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, being understood that modifications may be made within the scope of the claims without departing from the spirit'of the invention. y

In the drawings forming part of this application,

Figure 1 is a view in elevation, showing a gate and portions of the fencing between which the gate structure is installed or mounted. c Y

Figure 2 is a vertical section thru the devices controlled by the Vgovernor of Figure 1, for retarding the speed of the drum, and.v

the return of the gate to vertical closed position, after having been thrown to horizontal and open position by the impact of -a vehicle' driven against the gate. The gate may l however be otherwise controlled. J

. Figure Sis a section on line 3-'3 of Fig-y ure 1.

Figure 4 shows the ratchet mechanism in section and elevation. n v Y Figure 5 is a section on line 5-5 of Figure 1, showing slabs or boards extending between vertical channel bars, employed in the construction of the gate. 7

A rate post 10 has connected therewith a plurality of wires 11, and another gate post 12, considerably higher than the post just mentioned, is connected with the sectionof fencing shown at 13. Posts 10 and 12 are each mounted in or on a suitable base 14, be.- low thev surface of the ground.

Another post 15 is mounted in the position illustrated, and constitutes a part of a frame of which the upper element 16 forms a member, this element 16 having connectionwith post 12 andalso having connectionata point V17 with a post 18.

l The ygate Vincludes upper and lower horizontalbars 2Ol and 21, the vlower bar being formed with extensions mounted for rotation inthe bea-rings 22 connected with posts 10 i and 12. Thega'te thus mounted is adapted" to'V move about alower horizontal axis, and to liehflat whenin'open position, from which position it automatically:returns to verticaland closed position.,-

A pulley wheel 24 is mounted at the `upper end of post 12,'and a cable 25 'is connected with the lgate at `26, and passes kover* pulley 24 and thence around pulley 27, from which point it passes to the drum 28 mounted for ro- VVith the foregoing and other objects in tation about the axis29. Acable 25has its end portion 25 connected with weight or counterbalance 30, and this element will move to the l ity to the full line position of Figure 1 when f a vehicle driven against and onto the gate has passed over the latter, so that there is no weight or pressure preventing the automatic return of the gate to closed position.

In order to provide a'suitable'track or the like for the wheels of the vehicle, I connect. the upper and lower bars 20 and 21 of the gate by means 'of channel elements such as 33, these being arranged in two pairsas shown in Figure 1, and between theelements of each pair,

I mount boards or the like shown at 34, so that a propersurfaceis provided, yof such charac- `ter that in reality tracks are'forined.

Rotating with the drum 28 upon the return movement of the gate is a shaft 36 controlling a standard form of governor shown at 37, which in turn controls-the position of the friction disk 38, which will engage disk 39vwhen the arms of the governor rise too far, so that the action of spring'40 is overcome, and the disk 38 is forced downwardly. Disk39 constituting. the stationary element is carried by lthe upper portion of the frame forming ar part of the gate mounting structure.

Shaft 36 carries a pinion 41 meshing with the gear wheel 42, said gear wheel carrying a pivoted and spring-held pawl or dog 43 adapted to engage the internal teeth '44 of the drum 28. Thedruin is free to rotate during the opening movement of the gate, and independently ofthe gear wheel 42, but upon rotation ofthe drum in the other direction, incident to t-he downward movement of the counter-balance 30, the dog 43 will engage the teeth Wheel ivillrotate with the drum, and this gear Wheel 42 Will drive pinion 41 andshat ot' 5 the governon-excessive speed being checked,

Vas before indicated, When the arms or `the' governor rise sufficiently to cause disk 38 to contact with stationary disk 39p;

vHaving described the 1 invention What is claimed is p p 1. The combination vivitha gate mounted for movement about a horizontal axis, to open and closed position, of flexible means connected With the at its upper portion, a device for placing tension on the flexible means, a governor controlled brake, a drum over which the flexible means passes, and means for operating the governor by the movement of the drum in one direction.

,2. The combination With a gate mountedVV for movement about a horizontal axis, to open and closed position, of flexible means connected with the gate at its upper portion, a device tor placing tension on the ieXible means, 'a

. governor controlled brake, a drum over Which the flexible means passes,

y a shaft for the governor,

and paWl' and ratchet mechanism operatively connected With the drum and shaft.

3 The combination' with agate mounted for movement about a horizontal axis, to open and closed position, of` a cable connected with the upper portion of agate, a Weight connect-V ed with one 'end ,oiE the cable, a drum over which the cable passes,a gear Wheel, a shaft and pinion driven by the gear Wheel, a gover-1 nor operatively connected with the shaft, means for retarding the speed ofthe shaft upon the operation of the governor, and paivl and ratchet mechanism between said drum and gear Wheel.

In testimony whereof I my signature.
